Problems linking to calloc

[Mark Mussetter]

Hi everyone,

I am running rtems-4.6.0pre5 on a motorola 5272.  I am also going to run 
Microwindows on top of rtems.  I can get a clean build of Microwindows for 
rtems, but if I try to build any demos, I get errors from the linker saying 
that it can't find calloc, rtems_semaphore_obtain, and others.  We do have 
the code for these functions in the rtems tree, but they aren't getting 
linked in for some reason.

Is there a library that needs to be linked in that we are missing?

Below is a clip from the build log:
<SNIP>

and on and on and on......

Thanks for any help you might provide,
